As organic fruit and vegetables attract a higher price on the market, this can lead to economically motivated fraud through mislabeling produce as “organic” when they have been grown using synthetic fertilizer.

Laboratories need an analytical technique that can differentiate organic and non-organic grown fruit and vegetables: this can be achieved using the nitrogen isotope fingerprints measured using the EA IsoLink IRMS System. Food and beverage samples have a fingerprint, a unique chemical signature that allows the product to be identified with IRMS. Using isotope fingerprints, food and beverage origin, authenticity and product label claims can be verified in a unique way. Isotope Ratio Mass Spectrometry (IRMS) works by detecting the “isotope fingerprint” of a sample, a unique chemical signature that changes from sample to sample.

When healthy people eat a low-gluten and fibre-rich diet compared with a high-gluten diet they experience less intestinal discomfort including less bloating, a new study shows. The researchers attribute the impact of diet on healthy adults more to change in composition of dietary fibres than gluten itself.
